(svn r16247) [0.7] -Backport from trunk:

Browse Source 
- Fix: [NoAI] Make sure AITunnel::BuildTunnel returns what the documentation says it does (r16244)
- Fix: [NoAI] CmdBuildTunnel could be called with invalid parameters from the API code, causing crashes later [FS#2875] (r16243)
- Fix: [NewGRF] ActionB should use the online parameters from GRFFile instead of the initial user-specified values from GRFConfig. Also use the values as they were set when the ActionB was executed, not as they are set when the message is shown (r16223)
- Fix: Possible crashes when quiting OpenTTD or forcing resizes/redraws of the screen during map generation [FS#2862] (r16220)
- Fix: Shared orders without orders were not properly converted causing corrupt/invalid orders when loading pre 0.7 savegames [FS#2878] (r16214)
